Implementation of the Traffic Light System in Norwegian salmon aquaculture - success or failure for whom?
(Master thesis; Mastergradsoppgave, 2019-05-15)Since Norwegian Atlantic salmon aquaculture developed into a viable industry in the 1960s, it has grown into one of Norway’s most important sectors. A crucial factor influencing this growth has been the development of a management system which has facilitated the growth in an advantageous way. In the latter part of 2017, a new aquaculture management system started, called the Traffic Light System. ... -
Rising temperatures in a subarctic lake lead to increased somatic growth rates for Arctic charr (Salvelinus alpinus, (L.))
(Master thesis; Mastergradsoppgave, 2019-05-15)Cold water species living at high latitudes are expected to respond rapidly to climate change due to their sensitivity to increasing temperature. Water temperature strongly affects the ecology of fish, influencing food intake and conversion, and ultimately somatic growth rate. In a lake, somatic growth rates will also be contingent on food availability, which is negatively affected by fish abundance. ... -

It focuses on the changes and the differences between the Fisheries Partnership ... -
Modelling the bycatch reduction of a shrimp trawl with a combined Nordmøre grid and sieve panel configuration in the north east Atlantic deep-water shrimp (Pandalus borealis) fishery
(Master thesis; Mastergradsoppgave, 2018-06-01)The aim of this study was to investigate whether a sieve panel could be an alternative to the Nordmøre grid or if a sieve panel could combine with the Nordmøre grid regarding bycatch reduction while simultaneously maintaining shrimp retention in the Northeast Atlantic deep-water shrimp (Pandalus borealis) fishery. These gears are the two most established bycatch reduction devices used today in shrimp ... -
The Governance of the Angolan Industrial and Semi-industrial Fisheries. A Governability Assessment of the Commercial Fishery
(Master thesis; Mastergradsoppgave, 2018-05-15)ABSTRACT Angola has a very long coastline, and shares the Benguela Current Large Marine Ecosystem (BCLME) with Namibia and South Africa in the SADC region, one of the most productive LME in the world. The fauna is rich in small pelagic species, crustaceans and demersal fish community, explored by the commercial fishery. Understanding governability as a process of finding balance between the ... -
Egypt's success and Africa's failure - how to explain different development trajectories in (tilapia) aquaculture. A case study of the (tilapia) aquaculture industry development in Africa.
(Master thesis; Mastergradsoppgave, 2018-05-15)Abstract: As various concerned scientists and organisations such as the UN, the World Bank, WFP, and FAO point out, global food security progressively turns out to be one of the major challenges that our human family faces nowadays. Among other factors, this is a function of rapid population growth, decreasing global food production due climate change. As they have always been an important ... -

Different types of treatments have been tested and used to control lice on farmed Atlantic salmon with varying results. The aim of this systematic review is to examine effectiveness expressed as the reduction of the number of lice and ... -
Introducing insect-based salmon feed. From a nutritional, economic, legal and marketing perspective
(Master thesis; Mastergradsoppgave, 2018-05-15)The expansion of the aquaculture sector around the world has resulted in a growth of the demand for fishmeal (FM). Due to the limited sea resources, the price of FM has risen significantly in past years pushing the sector to find substitutes. In this context, insects attract more and more industrial and scientific attention as they have many advantages. First, with around one million species estimated, ... -

Suggested ways for improving the management of the Bay of Bengal shrimp trawl fisheries: A literature study on challenges and bycatch mitigation in shrimp trawl fisheries around the world and examples on how it is implemented in the management regimes in various nations.
(Master thesis; Mastergradsoppgave, 2018-04-14)India, Sri Lanka and Bangladesh have border with Bay of Bengal. Sri Lanka and India has good consciousness on bycatch situations in their part. But Bangladesh has very little intension on bycatch strategies. This paper has main intention to write about Bangladeshi part of Bay of Bengal on bycatch situation. As a littoral state of the Bay of Bengal, Bangladesh has ample coastal and marine resources. ... -
Drivers for compliance with fisheries rules. A systematic literature review
(Master thesis; Mastergradsoppgave, 2016-11-17)Many diverse conflicts are commonly found in a complex and dynamic system such as a fishery. Usual sources of conflicts are property rights conflicts, space utilization conflicts (e.g. fishers versus aquaculture), enforcement conflicts and conflicts that occur between the fishers and the government. The latter two may lead to issues with fisher’s compliance with state laws. This thesis examines ... -
Comparison of individual transferable quota in New Zealand and individual vessel quota in Norway
(Master thesis; Mastergradsoppgave, 2016-11-21)Since the introduction of licenses and quotas as important management instruments, Norway has established a system of non-transferable IVQs. The “cod-crisis” was a reason for the Nor- wegian Parliament to reject an ITQ system with a high degree of transactions. However, since the late 80s the IVQ regime have forced towards a market-oriented regime for the expansion of the transferability. The overall ... -

Perceptions of socio-cultural beliefs and taboos among the Ghanaian fishers and fisheries authorities. A case study of the Jamestown fishing community in the Greater Accra Region of Ghana
(Master thesis; Mastergradsoppgave, 2017-05-15)Small scale Artisanal fishing accounts for majority of fish catches in Ghana and it is increasingly substantial to the traditional fishing communities of the country. The existence of fishing dependent communities in Ghana has predominantly been intertwined with the existence of socio-cultural beliefs and taboos. As an attempt to contribute to exploring how these socio-cultural beliefs and taboos ... -
What is the true influence of the red tide on the production, price and marketing of the Galician mussel?
(Master thesis; Mastergradsoppgave, 2017-08-14)In recent years, the Galician mussel industry has encountered an environmental factor capable of influencing its sea farming; the red tide. Its environmental and economic impact on mussel aquaculture is directly related to the duration of toxic processes. Therefore, in this work will be used the number of days of closure of production areas in order to analyze what is the true influence that red ... -
Bioaccumulation and effects of parent and alkylated PAHs in an Arctic marine amphipod (Gammarus setosus) originating from pristine and historically contaminated sites in Svalbard. Implications for sensitivity and adaptation
(Master thesis; Mastergradsoppgave, 2016-09-15)The objectives of the study were to assess the bioaccumulation and genotoxic effects of PAHs and their alkylated PAHs from marine diesel fuel and coal polluted sediments in two populations of Gammarus setosus. Testing whether the alkylated forms are bioaccumulating more than their parent compounds, the degree of oxidative stress and ulterior DNA SSBs in the amphipods, as well as possible adaptation ... -

Implementation of the Ecosystem Approach to Fisheries in the North-East Atlantic. A case study of how the Joint Norwegian-Russian Fishery Commission has worked with the EAF
(Master thesis; Mastergradsoppgave, 2015-08-15)The Ecosystem Approach in Fisheries (the EAF) became a worldwide trend. More and more countries are adopting and developing this trend with different rate of success. There is a widespread agreement about the necessity of a new fisheries management strategy, which is taking into account food web linkages and human activity, which may affect sustainability of ecosystem. However FAO’s framework ... -
Implementation of the Ecosystem Approach to Fisheries; an institutional solution in fisheries management. The case of the ground-fisheries IFMP, Canada.
(Master thesis; Mastergradsoppgave, 2015-06-05)Fisheries management institutions, call the shots in fisheries management. Coming at a time when, global fish stocks are experiencing decline at an ever increasing rate, sectorial single species approaches cannot be looked upon solely to provide sustainable fisheries. This is foremost because studies have revealed that, the problems associated with the management of stocks are manmade and have a ...
